• Third Alzheimer’s disease cohort (AD3) in the Phase 2 ABATE trial of anti-Abeta ACI-24.060 to reach 12 months of treatment in December 2025, with interim results expected early 2026
• Small molecule NLRP3 program now in IND-enabling studies, highlighting promise in early-stage pipeline
• Cash resources of CHF 127.1 million (USD157.6 million) as of June 30, 2025, provide funding into Q1 2027 excluding any potential milestone payments
  
  

Lausanne, Switzerland, August 5, 2025 -- AC Immune SA (NASDAQ: ACIU), a clinical-stage biopharmaceutical company pioneering precision therapeutics for neurodegenerative diseases, today reported results for the quarter ended June 30, 2025, and provided a corporate update.

Dr. Andrea Pfeifer, CEO of AC Immune SA, commented: “AC Immune is continuing to progress toward precision prevention of neurodegenerative diseases as we approach multiple value-inflection points through the rest of 2025 and beyond. Our industry symposium during the AD/PD™ conference focused on unlocking active immunotherapy for tailored prevention strategies highlighted the momentum of our three active immunotherapies in Phase 2 development. Interim results on ACI-7104.056, our wholly owned a-syn active immunotherapy, reinforced its best-in-class characteristics, showing strong immunogenicity and a favorable safety profile in early Parkinson’s disease. The two partnered programs, ACI-24.060 and ACI-35.030, are also progressing according to plan. In addition, our Morphomer® small molecule drugs targeting a-syn and tau and Morphomer®-antibody drug conjugates (morADC) were featured in several presentations at AD/PD™ 2025. In our exciting early-stage pipeline, ACI-19764, a novel Morphomer® small molecule inhibitor of NLRP3, has now entered studies to enable an Investigational New Drug (IND) filing.

“Our strong cash position provides funding into 2027, excluding potential milestone payments, and enables us to advance our robust pipeline focused on precision prevention of neurodegenerative diseases. Further interim results from Part 1 of the VacSYn trial of ACI-7104.056 are expected later this year, and the AD3 cohort in the ABATE trial of ACI-24.060 will reach 12 months of treatment around year end, with interim results thereafter. We also expect to file an IND for ACI-19764 this year.”

Q2 2025 and Subsequent Highlights:

• Reported interim safety and positive immunogenicity data from the Phase 2 VacSYn clinical trial evaluating ACI-7104.056, AC Immune’s wholly owned anti-a-syn active immunotherapy candidate, for the treatment of patients with early PD.
  • As presented at AD/PD™ 2025, treatment with ACI-7104.056 induced an average 20-fold increase in anti-a-syn antibodies after four immunizations compared to placebo background level.
  • Based on pharmacodynamic and biomarker interim results to be reported later this year, AC Immune may decide to initiate Part 2 of VacSYn, with the aim of establishing early proof-of-concept and identification of disease-specific biomarkers for rapid transition into a pivotal study.
• AC Immune’s therapeutic and diagnostic programs were featured in multiple presentations at AD/PD™ 2025.
• AC Immune hosted an industry symposium highlighting the company’s industry-leading pipeline of active immunotherapies for precision prevention of neurodegenerative diseases.
  
  

Anticipated 2025 Milestones

Analysis of Financial Statements for the Quarter Ended June 30, 2025

• Cash Position: The Company had a total cash balance of CHF 127.1 million (CHF 165.5 million as of December 31, 2024), composed of CHF 25.7 million in cash and cash equivalents and CHF 101.4 million in short-term financial assets. The Company’s cash balance provides sufficient capital resources into Q1 2027, excluding potential milestone payments.
• Contract Revenues: The Company recorded CHF 1.3 million in contract revenues for the three months ended June 30, 2025, compared to CHF 0.7 million in the comparable prior period. For the three months ended June 30, 2025, our contract revenues of CHF 1.3 million were related to the efforts made under the agreement with Takeda.
• R&D Expenditures: R&D expenses for the three months ended June 30, 2025, were CHF 16.8 million compared to CHF 17.1 million in the comparable period in 2024. The decrease was primarily due to reduced activity in early-stage discovery programs, as well as lower expenses incurred on ACI-7104.056. These reductions were offset by higher costs in the Morphomer Inflammasome program (ACI-19764).
• G&A Expenditures: G&A expenses, in comparison to the comparable period in 2024, decreased by CHF 0.7 million to CHF 3.9 million for the 3 months ended June, 30, 2025. The decrease was primarily driven by a decrease in legal fees related to business development and licensing activities which were executed in the prior period.
• IFRS Loss for the Period: The Company reported a net loss after taxes of CHF 21.2 million for the three months ended June 30, 2025, compared with a net loss of CHF 22.8 million for the comparable period in 2024.
